LEN'ES FOR FUJI S - 2

[sampson]

Does anyone know just what is a really great sharp professional lens I can use to do wedding & portrait photography ? I here alot about Sigma,
Nikon len'es , and I do own a few, but I don't seem to be getting really sharp images from most of them, and would like some help in giving me the direction I need to go to achieve sharpness in my images. Perferably a multi millimeter lens would be what I'm looking for. Thanks in advance !!
